DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The making and using of embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that may be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

The advent of cloud-based networking has complicated the ability of future wireless networks to satisfy expected demands for higher throughput, lower latencies, lower energy, lower costs, and drastically more numerous connections. Cloud-based networking fundamentally redefines the endpoints and the time frame for which network services are provisioned. It requires the network be much more nimble, flexible, and scalable. Thus, technologies such as network function virtualization (NFV) and software defined networking (SDN) have become increasingly important in building future wireless networks. NFV enables network functions that are traditionally tied to hardware to run on a cloud computing infrastructure in a data center. Although the separation of the data plane, the control plane, and the management plane may not be feasible in the commercial cloud, the separation of those network functions from the hardware infrastructure will be a cornerstone of future wireless network architectures. One benefit is the ability to elastically support network functional demands. SDN is an architectural framework for creating intelligent programmable networks, where the control planes and the data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the application.

It is realized herein that a framework is needed for future wireless network operation that comprehends the prevalence of virtual networks and centralized control of resources. A virtual network (VN) is a collection of resources virtualized for a given service. It is realized herein that a framework of management plane functionality is needed to guide design and implementation of future wireless networks. It is further realized herein the framework can identify management plane functionality, include management plane interfaces, and include operation procedures. Management plane functionality can include infrastructure management, device connectivity management, customer service management, and status analysis management, among other functionality.

Infrastructure management functionality provides management capability for infrastructure topology adaptation according to network congestion and traffic load. Infrastructure management functionality allows integration of wireless networks of multiple providers. It also provides for spectrum management of a radio access network (RAN) and spectrum sharing among various co-located wireless networks. Infrastructure management also includes access (MAP) management and air interface management.

Device connectivity management functionality provides management capability for per-device attachment to the wireless network, including media access control (MAC) status, location tracking, and paging. Device connectivity management functionality includes defining customized and scenario-aware location tracking schemes. Device connectivity management functionality also provides for a software-defined and virtual per-mobile-user geographic location tracking entity and a triggering of user-specific data plane topology updates. Device connectivity management functionality also provides user-specific virtual network migration and location tracking as a service (LTaaS). A UE's location is relative to the network or, more specifically, relative to a set of potential network nodes that could provide network access to the UE. LTaaS provides UE location tracking and location information to the UE's home operator or a global UE location information management center, which is generally managed by a third party. The information can then be accessed and used by other operators, VN operators, and others.

Customer service management functionality provides management capability for customers' private information, authorization of device access, device security, and negotiation of service quality of experience (QoE). Customer service management functionality includes per-service QoE management as well as charging services. Customer service management functionality also provides customer specific context for connections and services. This includes QoE monitoring, charging, and billing.

Status analysis management functionality provides management capability for on-demand network status analysis and QoE assurance. More specifically, status analysis management functionality provides for management of on-demand network status analytics, management of on-demand service QoE status analytics, and data analytics as a service (DAaaS).

It is further realized herein the management plane functionality required in a wireless network can vary among devices and can depend on a device's state. The various devices in a wireless network include customer devices, i.e., user equipment (UE), and operator nodes, i.e., base stations or radio nodes. It is realized herein that a customer device can be powered on or off, and, while on, can be active or idle, all of which is referred to as the customer device's state. It is also realized herein that an operator node can also be powered on or off and, while on, can be active, idle, or inactive. Furthermore, an operator node's state can vary among its respective subsystems. For example, an operator node's access subsystem may be active, idle, or inactive while powered on, while the operator node's backhaul subsystem may be active or inactive. Similarly, the operator node's sensor subsystem may be active or inactive while powered on.

While in an active state, a UE continuously searches and monitors for feedback channel quality indicators (CQI). A continuous process is one that is carried out at every transmission interval. For example, if the transmission interval is 1 millisecond, then the UE searches and monitors periodically, where the period is 1 millisecond. The UE also continuously sends signals enabling uplink (UL) CQI estimation. On the network side, while the UE is active, a VN-active is established. The configuration of the VN-active depends on the UE's mobility, required QoE, and network status. Also, while the UE is active, the network maintains contexts above and below layer-2, including automatic repeat request (ARQ) and hybrid ARQ (HARQ) below; and flow/service ID mapping to ID defined in the access link (AL), location, states, authentication keys, sessions, and QoE above.

While in an idle state, the UE has an idle state ID and remains attached to the network. The UE continuously searches and monitors the network for measurement purposes and location updates. The UE may also perform mobility monitoring/tracking and location synchronization with the network. In certain embodiments, the UE carries out network monitoring conditionally. The UE also transmits and receives short data bursts without going back to active state. On the network side, while the UE is idle, a VN-idle is established. The configuration of the VN-idle depends on the UEs mobility, required QoE, and network status. The VN-idle can have no dedicated physical network resources or can have partially dedicated physical network resources, for example, between a user-specific virtual serving gateway (v-u-SGW) and other gateways (GWs).

FIG. 1 is a block diagram of one embodiment of a logical functional architecture 100 for a wireless network. Architecture 100 separates the wireless network into a data plane 110, a control plane 120, and a management plane 130. Data plane no transports network traffic among the various network nodes and UEs attached to the wireless network. Control plane 120 makes network resource assignment decisions for customer service traffic and transports control signals among the various network nodes and UEs. Management plane 130 provides various management and administrative functionality for the network. Interfaces exist among management plane 130, control plane 120, and data plane no, enabling each to carry out its respective functionality. Additionally, control plane 120 has an application programming interface (API) 122 that allows various applications 140-1 through 140-N to access control plane 120.

Architecture wo also includes various databases that are occasionally accessed by management plane 130 in carrying out its functionalities. These databases include a privacy network database 150, a customer service information database 152, a customer device information database 154, an infrastructure database 156, and an infrastructure abstraction database 158. Privacy network database 150 is a repository for topology information, node capabilities, states, and security information. Customer service information database 152 is a repository for authentication and security information related to customer devices, i.e., UEs. Customer device information database 154 is a repository for capabilities, locations, and states of customer devices. Infrastructure database 156 is a repository for network topology, node capabilities, and states. Infrastructure abstraction database 158 is a repository for various infrastructure abstractions within the wireless network.

In architecture 100, management plane 130 provides various functionalities through respective control blocks, including: an infrastructure manager 132, a data analyzer 134, a customer service manager 136, and a connectivity manager 138. Management plane 13o, in certain embodiments, can provide additional functionalities, such as content service management, which is responsible for defining content caches in the radio access network (RAN), configuring cache-capable network nodes, and managing content forwarding.

Infrastructure manager 132 is responsible for integrating network nodes from various wireless network providers. Infrastructure manager 132 is also responsible for spectrum management for RAN backhaul links and access networks, as well as spectrum sharing among co-located wireless networks. Infrastructure manager 132 also provides access map management and air-interface management, among other functionalities. Data analyzer 134 is responsible for data analytics related to the wireless network. These analytics include managing on-demand network status, managing on-demand QoE, and providing data analytics as a service (DAaaS), among other functionalities. Customer service manager 136 is responsible for customer aspects of service, including QoE, charging, and customer information, among other functionalities. Connectivity manager 138 is responsible for location tracking and synchronization, pushing topology updates to users, VN migration, and providing location tracking as a service (LTaaS), among other functionalities.

Infrastructure manager 132, data analyzer 134, customer service manager 136, and connectivity manager 138 can be implemented in one or more processors, one or more application specific integrated circuits (ASICs), one or more field-programmable gate arrays (FPGAs), dedicated logic circuitry, or any combination thereof, all collectively referred to as a processor. The respective functions for Infrastructure manager 132, data analyzer 134, customer service manager 136, and connectivity manager 138 can be stored as instructions in non-transitory memory for execution by the processor.

FIG. 2 is a block diagram of one embodiment of a management plane hierarchical architecture 200. Architecture 200 includes a top level management plane 210 having second and third levels beneath it. Top level management plane 210 coordinates among second level management planes 220-1 through 220-N. Each of second level management planes 220-1 through 220-N is responsible for coordinating among its respective third level management planes. For example, Second level management plane 220-N coordinates among third level management planes 230-1 through 230-M. At each level of architecture 200, the management plane can include up to the full functionality for management plane 130 of FIG. 1. Top level management plane 210 and other upper-level management planes in architecture 200 also include coordination capabilities for coordinating among respective lower-level management planes. The division of the management plane into the various levels of architecture 200 can be done in a variety of ways, including by geographic zones, virtual networks, and service types. In certain embodiments, within a single level of architecture 200, peer management planes can also communicate with each other. For example, second level management plane 220-1 could communicate with second level management plane 220-2.

FIG. 3 is a block diagram of one embodiment of a network node 300. Network node 300 includes access subsystems 310-1 through 310-i, backhaul subsystems 320-1 through 320-j, and sensor subsystems 330-1 through 330-k. Access subsystems 310-1 through 310-i can include single or multiple access links. Similarly, backhaul subsystems 320-1 through 320-j can include single or multiple backhaul links. The various subsystems of network node 300 can be in different states at a given time. Each of the subsystems can be powered on and off independently, and transition among various states independently. Each of access subsystems 310-1 through 310-i can be in an active state, idle state, or inactive state while powered on. Each of backhaul subsystems 320-1 through 320-j can be in an active state or an inactive state while powered on. Each of sensor subsystems 330-1 through 330-k can be in an active state or an inactive state while powered on. Each of these subsystems is inactive while powered off.

The operation of the subsystems of network node 300 varies with each subsystems current state. An access subsystem, while active, carries out continuous downlink (DL) transmissions, discontinuous radio frequency (RF) transmissions (e.g., pilots and reference signals), and continuously receiving and monitoring UL transmissions. In the idle state, the access subsystem carries out no DL RF transmissions, but continuously carries out UL receiving and monitoring. While inactive, the access subsystem shuts down RF activity, including DL and UL.

A backhaul subsystem, in the active state, carries out RF transmissions and continuously receives and monitors RF transmissions. While inactive, the backhaul subsystem shuts down RF activity. Similarly, a sensor subsystem, sometimes referred to as an out-of-band sensor subsystem, carries out continuous and discontinuous RF transmissions and continuously receives and monitors RF transmissions while active. While inactive, the sensor subsystem shuts down RF activity.

FIG. 4 is a flow diagram of one embodiment of a method of managing a wireless network. The method begins at a start step 410. At an infrastructure management step 420, a management plane manages an infrastructure topology for the wireless network. The wireless network's infrastructure topology generally includes a plurality of network nodes. At a connectivity management step 430, the management plane manages connections of UEs to the wireless network according to the infrastructure topology. At a customer service management step 440, the management plane manages services provided to the UEs over their respective connections. At a data analytics step 450, the management plane performs analysis on performance metrics and manages the corresponding analytics. These steps are generally carried out in parallel, however, under certain circumstances, there are sequential aspects among the steps. The method then ends at an end step 460.

FIG. 6 is an illustration of a procedure 600 representing operation of an embodiment management plane when a customer device enters the network. Procedure 600 is carried out among various components of the management plane, including customer service manager 136 and connectivity manager 138, both of FIG. 1. Procedure 600 is also carried out among a customer device 610, control plane 120 of FIG. 1, and data plane 110, also of FIG. 1. Customer device 610 powers on at step 620 and begins DL acquisition and UL synchronization procedures at step 622. Customer device 610 then sends ID and location information, at step 624 to control plane 120 for registration at step 640. The location information is passed from control plane 120 to connectivity manager 138 where it is registered at step 670. Connectivity manager 138 stores the location information in the customer device information database. Connectivity manager 138 then begins synchronizing location tracking with customer device 610 at step 672. The ID information is passed to customer service manager 136 for authentication at step 660. Authentication is carried out according to the ID information and information in the customer service information database. Authorization is then sent from customer service manager 136 to customer device 610, which is received at step 626. Control plane 120 establishes a VN at step 642, which is represented by VN-idle in data plane no at step 650. Customer device 610 then prepares for idle at step 628, and enters the idle state at step 630.

FIG. 7 is an illustration of a procedure 700 representing operation of an embodiment management plane when a customer device is idle without burst traffic. Procedure 700 begins with customer device 610 in an idle state at step 710. Customer device performs DL monitoring and location tracking at step 712. At step 714, a location update is made and is synchronized with connectivity manager 138 at step 720. Connectivity manager 138 updates the location in customer device information database. Connectivity manager then sends a location update to control plane 120 at step 730. Control plane 120 then updates the VN-idle at step 740. Connectivity manager 138 proceeds with location tracking at 722 and customer device 610 resumes DL monitoring and location tracking at step 716.

FIG. 8 is an illustration of a procedure 800 representing operation of an embodiment management plane when a customer device is idle with upstream burst traffic. Procedure 800 begins with customer device 610 in an idle state at step 810. Customer device 610 performs DL monitoring and UL synchronization at step 812. At step 814, customer device 610 sends a traffic burst to data plane no. Data plane no forwards the traffic burst to a u-v-SGW using VN-idle. Customer device 610 remains in idle at step 816.

FIG. 9 is an illustration of a procedure 900 representing operation of an embodiment management plane when a customer device is idle with downstream burst traffic. Procedure 900 begins with customer device 610 in an idle state at step 910. Customer device 610 performs DL monitoring and UL synchronization at step 912, and monitors for paging at step 914. Data plane no receives burst traffic at a v-u-SGW and filters it at step 940. The v-u-SGW notifies control plane 120. Control plane 120 instructs connectivity manager 138 to page customer device 610 at step 950. Customer device 610 acknowledges the page and measures CQI at step 916. According to the page, control plane 120 makes a traffic decision at step 932 and instructs data plane no to forward the burst at step 942. The burst is received by customer device 610 at step 918, and customer device 610 continues to idle at step 920.

FIG. 10 is an illustration of a procedure 1000 representing operation of an embodiment management plane when an upstream session triggers a customer device to transition from idle to active. Procedure 1000 begins with customer device 610 in an idle state at step 1010. Customer device 610 performs DL acquisition and UL synchronization at step 1012. Customer device 610 submits a session request to control plane 120 at step 1014. Control plane 120 processes the request at step 1030 and begins negotiation with customer service manager 136 at step 1040. Customer service manager 136 and control plane 120 negotiate a QoE for customer device 610 according to information in the customer service information database and make a QoE guarantee at step 1016. In an alternative embodiment, customer service manager 136 negotiates directly with customer device 610 to establish the QoE guarantee. Control plane 120 establishes a VN at step 1032 according to the negotiated QoE, location information, and network status. VN-active 1050 is created in in data plane no at step 1050. Customer device 610 then transitions to an active state at step 1018 and makes an upstream transmission via data plane no at step 1052. While customer device 610 is in the active state, customer device 610 makes occasional location updates at step 1020 and connectivity manager 138 synchronizes location at step 1060 and updates the location in the customer device information database.

FIG. 11 is an illustration of a procedure 1100 representing operation of an embodiment management plane when a downstream session triggers a customer device to transition from idle to active. Procedure 1100 begins with customer device 610 in an idle state at step 1110. Customer device 610 makes a location update at step 1112 and connectivity manager 138 synchronizes location at step 1130. Connectivity manager 138 updates the location in the customer device information database. Customer device 610 continuously monitors for paging at step 1114. A session request is received at control plane 120 at step 1140. Control plane 120 and customer service manager 136 then negotiate QoE requirements at step 1150 according to information in the customer service information database. Control plane 120 makes a location inquiry to connectivity manager 138 at step 1142. Connectivity manager 138 then pages customer device 610 at step 1132. Customer device 610 acknowledges the page and measures CQI at step 1116. Connectivity manager 138 updates the location for customer device 610 and passes it to control plane 120. Control plane 120 establishes a VN at step 1144 according to the location information, QoE requirements, and network status. A VN-active is created in data plane 110 at step 1120. A downstream transmission is then made at step 1122, triggering customer device 610 to transition to an active state at step 1118.

FIG. 12 is an illustration of a procedure 1200 representing operation of an embodiment management plane for adapting a topology. Procedure 1200 is carried out over various elements of the management plane, including infrastructure manager 132, data analyzer 134, and connectivity manager 138, all of FIG. 1. Procedure 1200 is also partially carried out by customer device 610 and data plane 110 of FIG. 1. Data analyzer 134 generates a congestion and traffic report at step 1210 and delivers the report to infrastructure manager 132. Infrastructure manager 132 checks the current network topology at step 1220. Infrastructure manager 132 then adapts the topology at step 1222 according to the congestion and traffic report and information in the infrastructure database. Adaptations can include bandwidth increase, new backhaul links, and modifying existing backhaul links, among other adaptations. At step 1224, infrastructure manager 132 configures network nodes 1230 affected by the adaptation. Configuration can include beam/sector configuration and access link configuration, among other parameters. Infrastructure manager 132 then issues an infrastructure update at step 1226. Connectivity manager 138 receives the infrastructure update at pushes an updated infrastructure map to customer device 610 at step 1240. Customer device 610 can be in an idle or active state.

FIG. 13 is an illustration of a procedure 1300 representing operation of an embodiment management plane for integrating private network nodes into the network. Procedure 1300 begins with a congestion and traffic report from data analyzer 134 at step 1310. The report is received by infrastructure manager 132. Infrastructure manager checks the current network topology at step 1320. According to the congestion and traffic report, infrastructure manager 132 negotiates with private nodes 1330 to integrate them into the data plane 110 at step 1322. The infrastructure database is updated at 1324 and affected nodes 1332 are updated at step 1326. Infrastructure manager 132 issues an infrastructure update at step 1328. Connectivity manager 138 receives the infrastructure update and pushes an updated infrastructure map to customer device 610 at step 1340. Customer device 610 is in an idle state at step 1350.

FIG. 14 is an illustration of a procedure 1400 representing operation of an embodiment management plane for on-demand QoE assurance. Procedure 1400 is carried out among customer device 610, control plane 120, data plane 110, data analyzer 134, and customer service manager 136. Procedure 1400 begins with customer device 610 in an active state at step 1420. Data analyzer 134 schedules QoE reporting at step 1410. QoE reporting can be scheduled with active customer devices, selected network nodes 1430, or both. Customer device 610 generates QoE metrics at step 1422 and sends them to data analyzer 134. Selected nodes 1430 in data plane no generate QoE metrics at step 1432 and send those to data analyzer 134 as well. At step 1412, data analyzer analyzes the QoE metrics from customer device 610 and data plane no to generate a QoE status. The QoE status is sent to control plane 120 at step 1440. Control plane 120 negotiates QoE at step 1442 with customer service manager 136 at step 1450. The negotiation is done according to the QoE status generated by data analyzer 134.
